Re: Mars One - Unethical?
All the good ideas in US manned spaceflight were formed from proteins that came from beef, which is why the Western Cattlemen's Association is really responsible for all the progress made thus far, and only that pioneer ranching spirit can keep spaceflight progressing without losing complete continuity with what came before. Beef.
Wait, is this really true?
